One was a male and one was a female and I guess her name was "Deb-uh" ( ha)Luna it seems is a were-bat.

Pg 93 LDID "This little bat saved your life tonight, for real?" "Yes." I was absolutely sincere about that. "Luna saved my life."Now as to what animal Debbie Pelt shifts into, well- that is one of the infamous Charlaine Harris ( I really love the little inaccuracies, myself-i think they are charming ) Sookie books mistakes.

In two different books, Charlaine says Debbie Pelt is two different types of were- animal.

Page 36 DD Okay. Debbie Pelt, werefox, had been adopted. I'd learned that the Weres were prone to fertility problems, and I assumed that the Pelts had given up on having their own little Were...

Page 144 DTTW "Oh, I can't," she said bitterly. "I've been abjured. I can't change with Alcide's pack anymore. They have license to kill me, if I do.""What did you shift into, anyway?""Lynx."That was appropriate.

Charlaine was asked this questions last month in Houston you can hear her own answer here

The answer was "I made a mistake " I hope this helps clear this mystery up a little.

Also from DTTW

"And what does she shift into?" Shape-shifters had a choice, but there was one animal each shifter had an affinity for, her habitual animal. A shape-shifter could call herself a "were-lynx" or a "were-bat," if she was out of hearing range of a werewolf. Werewolves objected very strenuously to any other two-natured creatures who termed themselves "Were."
